42 bind-正反向区域配置

dns配置流程

• 1.配置区域
• 2.配置区域数据库文件
• 3.服务重载

正向解析

1.配置解析一个正向区域

vim /etc/named.rfc1912.zones
zone "leicc.com" IN {
        type master;
        file "leicc.com.zone";
};

2.建立区域数据文件

vim /var/named/leicc.com.zone

$TTL 3600
@       IN      SOA     @  ADMIN1.leicc.com (
                20180812
                1H
                10M
                3D
                1D)
        IN      NS      ns1
        IN		A		192.168.113.129  #匹配不输入www
ns1     IN      A       192.168.113.128
www     IN      A       192.168.113.129
www     IN      A       192.168.113.128
web     IN      CNAME   www
* 		IN		A 		192.168.113.149   #匹配默认

3.检查语法

• named-checkconf
• named-checkzone leicc.com /var/named/leicc.com.zone
• rndc reload

4.测试

​ dig -t A web.leizhichao.com @192.168.113.128

; <<>> DiG 9.9.4-RedHat-9.9.4-61.el7 <<>> -t A web.leizhichao.com @192.168.113.128

;; flags: qr aa rd ra; QUERY: 1, ANSWER: 2, AUTHORITY: 1, ADDITIONAL: 2

反向解析

1.定义区域

zone "113.168.192.in-addr.arpa" IN { 、
	type master; 
	file "leicc.com.zone"; 
 };

2.定义数据库文件

vim /var/named/leicc.com.zone
$TTL 3600   
@       IN      SOA     ns1.leicc.com.  ADMIN1.leicc.com. (
​                20180812
​                1H
​                10M
​                3D
​                1D )
​        IN            NS        ns1.leicc.com.

128     IN            PTR       ns1.leicc.com.
127     IN            PTR       mx1.leicc.com.
126     IN            PTR       bbs.leicc.com.

3. 验证结果

dig -x 192.168.113.128
